We, acting by command of and in behalf of the Emperor of Japan, the Japanese Government and the Japanese Imperial General Headquarters, hereby accept the provisions set forth in the declaration issued by the heads of the Governments of the United States, China, and Great Britain on 26 July 1945 at Potsdam, and subsequently adhered to by the Union of Soviet Socialist Republics, which four powers are hereafter referred to as the Allied Powers. ....
...... .... and so on.
And yet........... the USA actually never accepted the Japanese surrender: as such both nations are still at war with each other! Photographs of MacArthur (Supreme Commander for the Allied Powers) at the signing ceremony show that the USA flag was actually displayed backward — reverse side showing, with the stars in the upper right corner. It is generally accepted in learned quarters that the USA had never forgiven Hirohito for Pearl Harbo(u)r, thus the US can, at any point in the future, strike back in revenge at one of the major Japanese ports, such as Yokohama, Kobe or Osaka.
The only thing holding the might of the USA back is the extent of their present trading partnership with the Japanese. But this could change as China tightens a grip on world markets previously dominated by their near neighbour and great enemy.
